This research explores the challenges and drivers of Geographic Information Systems (GIS) affordance actualization within the Ministry of Land and Survey, Yola, Nigeria. The problem at hand is the underutilization of GIS technology in many public organizations, often resulting in failed projects and misfit due to cultural inclinations. To address this issue, Activity Theory was employed as a theoretical framework, innovatively applying it to the interpretation of human-technology interactions within a public sector setting. An in-depth interpretive research study at the Ministry of Land and Survey (MLS) was conducted, focusing on the sub-unit triangular and subject-cascaded models guided by integrated nested Activity Theory. The research reveals novel insights into the application of GIS in public organizations. The findings underscore the critical role of factors such as funding, legitimization, technology (tools), user cognition, geo-visualization, spatial infrastructure, and outcomes in facilitating GIS affordance actualization. These elements have been redefined within the context of land administration in public organizations. The research introduces two new theoretical constructs, "Spatial Data Infrastructure" and "Geo-visualization," further extending the integrated Activity Theory constructs. The importance of this study lies in its potential to inform GIS professionals, developers, and policymakers. The newly developed mid-level theoretical model, Spatial Information Affording Approach (SISAA) offers a comprehensive framework for designing effective GIS systems that streamline land transactions, enhance revenue generation, reduce land disputes, and bolster the overall integrity of land administration in public sectors. This research contributes not only to the Nigerian context but also holds relevance for public organizations worldwide that use GIS in land management. In conclusion, this study bridges a significant gap in the current body of knowledge by providing a spatially enabled theoretical framework for GIS applications in culturally organized public organizations. It has the potential to drive improvements in land administration and promote the successful implementation of GIS in the public sector, aligning with global agendas such as the Sustainable Development Goals (SDGs).
